Can someone please explain to me what happens under the following conditions. I have set a minimum SoC limit via ESS of 40%. If I then have loadshedding and the load drains the battery continuously below the 40% limit. When and what happens if the loadshedding continues way beyond the expected few hours? ( to the battery and to the inverter - Victron 48/10000). Thank you. Colin
If there is no battery BMS (which also might turn the inverter off), the Inverter should shutdown/turn off when the Dynamic cutoff voltage is reached. So make sure you set those voltages (there are more voltages, depending on load) properly for your battery.
The FW has a CAN BMS from orion, it will disable discharge if you get too low. Else, ESS will recharge it from grid to the minimum when power returns or the inverter will power off at the minimum soc set, and power on again once the minimum restart threshold was hit. Plenty of protection.
Thanks for your replies.
Does your replies mean that the system will manage itself off and back on again when the grid electricity becomes available.
Is the point where the battery switches itself off at a %(like min SoC) or is it when it gets to a low voltage level.
Does that mean the lights go out when this point is hit. Again. will it all come back by itself
Minimum SOC set in ESS is ignored if there is no grid.
The only safeguards in this situation are the battery BMS (if it exists) and the Dynamic cut off voltages set in ESS (in the inverter).
Do you also have PV panels and a MPPT charger?
